FEEDING MECHANISM FOR FIBER-TREATING MACHINES.

No. ceases.

To all whom it may concern:

I mg mechanism, and having chain and guide mechanism for supportin guiding, F strengthening or operating the eltmechanism.

The principal object of the invention is to provide a simple, economical and etlicient feeding mechanism for machines for breaking, scutching, cleaning or treating hemp, tiara, ramie, jute, sisal or other fibrous stalks or material.

A further object of the invention is to provide a feed belt or belts of preferably compressible material with suitable improved means for supporting, guiding and operating the same and adapted to minimize the stretching ofand reduce the strains upon the belts and hold them in eflicient operative engagement with the fibrous material to be fed thereby.

l urther objects are to provide preferably compressible or elastic flexible feeding belts with supporting, guiding and belt operating chains mounted upon sprocket wheels and in engagement. with the belts and so constructed that all parts of the chains and belts which are in contact with each other will move in unison or at the same speed throughout their both around the wheels upon which the chains are mounted and from wheel to wheel thereby reducing the stretching of the belts, relieving them of muchof the strain to which they would otherwise be subjected, minimizing the friction and wear upon the parts and iucreasing their efficiency and durability in operation; to provide afeedlug-chain so constructed that it is adapted to support a feeding-belt, compressil'ile or in such pos1tn 1rthat the Specification of Letters Patent. Application filed July 27, 1907. Serial 110.385,?83.

pitch line or line between the inner compressed side or portion of theabelt and its outer tension or stretched side or portion will be in line with and more at all times at 'the same speed with the articulations or points of pivotal connections of the links of the chain when mounted upon sprocket wheels; to enable this to be accomplished in such a manner that the adjacent portions of the upper and lower feeding-belts may move in a straight line at the same speed and with the pitch lines of the belts the same distance from the centers of the supporting sprocket wheels as the points of pivotal connections between the links of the chain, the inner sides of the beltsbeing outside of the pitch line of the sprocket wheels and preferably outside of the peripheral points of the sprocket-wheel teeth, and to provide the necessary rigidity and strengthor a suitable backing and guide for the portions of the belts between which the material to be during the feeding operation.

'Other and further objects of the invention will appear from an examination of the drawings and the following description and claims.

The invention consists in the features, combinations and details of construction hereinafter described and claimed.
